Multi-Timeframe Trend Heatmap (EMA/RSI Based)

Multi-Timeframe Trend Heatmap is a compact visual indicator that shows trend direction across multiple timeframes at a glance.

You can choose between two trend detection methods:

✅ EMA: Price compared to an exponential moving average

✅ RSI: Overbought/oversold zone filtering (above 55 = bullish, below 45 = bearish)

🔍 How it works:

For each timeframe (up to 3), the script checks whether the trend is bullish, bearish, or neutral.

The result is shown as a heatmap using colored bars:

🟩 Green = Bullish

🟥 Red = Bearish

⬜ Gray = Neutral

✅ Features:

Select up to 3 custom timeframes (ex: 5min / 15min / 1h)

Choose between EMA or RSI trend logic

Works in a separate pane (non-overlay)

This indicator is especially useful for scalpers and intraday traders who want a quick and reliable overview of multi-timeframe alignment.
